Ruhollah Musavi Khomeini (17 May 1900 – 3 June 1989) was an Iranian cleric, politician, political theorist, and revolutionary who founded the Islamic Republic of Iran and served as its first supreme leader from 1979 until his death in 1989. He was the main leader of the Iranian Revolution, which overthrew Mohammad Reza Pahlavi and transformed Iran into a theocratic Islamic republic.
Born in Khomeyn, in what is now Iran's Markazi province, his father was murdered when Khomeini was two years old. He began studying the Quran and Arabic from a young age assisted by his relatives. Khomeini became a high ranking cleric in Twelver Shi'ism, an ayatollah, a marja' ("source of emulation"), a mujtahid or faqīh (an expert in fiqh), and author of more than 40 books. His opposition to the White Revolution resulted in his state-sponsored expulsion to Bursa in 1964. Nearly a year later, he moved to Najaf, where speeches he gave outlining his religiopolitical theory of Guardianship of the Jurist were compiled into Islamic Government.
